PNP_DETECTED_FATAL_ERROR (ca)

 PnP encountered a severe error, either as a result of a problem in a driver or

 a problem in PnP itself.  The first argument describes the nature of the

 problem, the second argument is the address of the PDO.  The other arguments

 vary depending on argument 1.

 Arguments:

 Arg1: 00000001, Duplicate PDO

     A specific instance of a driver has enumerated multiple PDOs with

     identical device id and unique ids.

 Arg2: b425d310, Newly reported PDO.

 Arg3: b42ca5d0, PDO of which it is a duplicate.

 Arg4: 00000000
